The strength of the current in the circuit is 0.5 A, the voltage on one of its sections is 50 V what kind of work does the electric current do in this section in 10 minutes.
I = 0.5 A.
U = 50 V.
t = 10 min = 600 s.
A -?
The work of electric current A in a conductor is determined by the Joule-Lenz law: A = I * U * t, where I is the current in the conductor, U is the voltage at the ends of the conductor, t is the time the current passes through the conductor.
A = 0.5 A * 50 V * 600 s = 15000 J.
Answer: when passing through a conductor, the current performs work A = 15000 J.
